DOOR-HOLDER.

Specification of Letters Patent.

Application filed May 14, 1908.

To all whom it may concern:

Be it known that we, CHARLES J. CALEY and HENRY G. Voronr, citizens of the United States, residing at New Britain, Hartford county, State of Connecticut, have invented certain new and useful Im rovements in Door-Holders, of which the fol owing is a full, clear, and exact description.

Our invention relates to improvements in door holding devices, the object being to provide a means whereby a door may be frictionally held in any desired position.

Heretofore door holders, in the majority of instances, have been in the nature of plungers or levers, carried by the door and arranged to engage the carpet or floor directly beneath the edge of the door. By such an arrangement there is grave danger of abrading the carpet or marring the floor. By the present invention the door is held independently of the floor and the danger of marring the wood-work is entirely eliminated.

The object of the invention is to accomplish this result in a simple and effective manner, and these objects we attain by the use of mechanism such as shown in the accompanying drawin s, in which Figure 1 is a side e evation; Fig. 2 is a plan view thereof; Fig. 3 is a side elevation, partly in section, of one portion detached; Fig. 4 is a plan view thereof; Fig. 5 is a vertical crosssection on the plane of the line x:c of Fig. 2; Fig. 6 is a plan view of a detail; Fig. 7 is a plan view of another detail.

Before describing the various details of the invention, we should say that the device is so constructed that it may be attached to a door after the manner of a hinge, its pivotal center being concentric with the ivotal centers of the hinges, so that as the oor is o ened the two members of the door-holding evice will swing in a manner similar to the hinge leaves. Obviously variations in design employed may be made.

11 the drawings we have conventionally shown the invention in one form, although this may be modified to suit the exigencies of any particular case.

The device includes two main parts, or hinge-like members.

12 represent the wings or leaves of such members, by which the same are connected respectively to a door or door casing. These wings l2 respectively carry the upper and lower case sections 34. These case sections inclose the friction mechanism.

5 is a central pivot.

5 is a supporting shoulder thereon located at approximately the line of division between the sections 34.

6 is a washer corrugated radially and normally seated upon the shoulder 5 7 is a plate arranged above the washer 6 and pressed down by a spring 8.

9 is a retaining nut at the upper end of the pivot 5, adapted to connect the parts 3 and 4.

10 is a cap overstanding the nut 9.

11 is a washer corresponding to the washer 6, and preferably corrugated in a similar manner. This washer 11 is arranged below the washer 6 and rests upon a rotatable block 12, rovided with an arm 12 projecting throug the side of the case section 4, and by which said block 12 may be partially rotated.

14-14 are cam surfaces or inclines upon the case section 4, upon which the block 12 is adapted to ride upwardly when rotated in one direction, the under side of the block, in the particular form shown, being recessed to provide space for said cams 1414. The groove in the side wall of the part 4, through whichth'e arm 12" projects, is arranged to afford sufficient clearance for the block 12 to ride up, carrying with it arm 12*. In the form shown, this groove is inclined to correspond to the inclines of the cams 14 (see Fig. 1). Each of the washers 611 is provided with an offset 15. The washer shown in Fig. 6 may represent either one of said washers 6 or 11. The projection 15 on each washer is adapted to extend into a vertical groove in the side wall of its respective case section 3 or 4, so that said washers 6 and 11 will turn only with their respective sections and not independently thereof.

Operation: As shown in Fig. 5, the block 12 is in its lower position and the washers 611 are out of engagement. In this position, obviously, no resistance is oifered to the free turning of the part 3 relatively to the part 4. When the block 12 is rotated so as to ride up the inclines of cams 14, the washer 11 will be brought up into engagement with washer 6, and will become frictionally locked thereto, so as to provide such a resistance that said parts 3 and 4 will be sufiiciently held against independent rotation. While the washers 6 and 11 may have of themselves sufiicient elasticity, we prefer to provide the s ring-pressed follower plate 7 to guarantee e ective action under al conditions. Now, assuming that it is desired to hold the door in a artially open position, the door is opene to the desired extent and then the operator merely throws the arm 12 into a osition to cause the block 12 to ascend and frictionally lock washer 1 1 against the washer 6. When this occurs the door will be held in its said partially opened position. Should unusual force be applied to the door to close it, the door may be closed without injury to the holding device, since the washers 11 and 6, being merely frictionally held, will slip and allow the door to close, although under all normal conditions this slippage will not occur. It will be seen at once that there is no danger whatever of injury to the woodwork or any part of the mechanism. If desired, an operating arm 12 might be provided so as to project from both sides of the case section 4, thus adapting the device to a double swinging door without further change, save that in this form of construction a propriate wings would necessarily be provi ed to adapt the holder to the door and door casing. In the particular form shown, each wing is composed of two slidable members. One part can be screwed to the door or door casing, while the other part may be adjusted to and fro. 16 represents any suitable device for holding these two parts in an adjusted position. By this adjustable means it is .very easy for a carpenter to line up the pintle of the holder with the pintle of the hinge on the door.

What we claim is:

1. In a door holder, two companion hinge leaves, a pintle therefor, means carried by said leaves and arranged to apply a frictional resistance between said leaves to hold the same in various positions of angular adjustment relatively to the intle, and a manually operable device for t rowing said friction means into and out of action without separatin said leaves.

2. n a door holder, two companion hinge leaves, a pintle therefor, means carried by said leaves and arranged to apply a frictional resistance between said leaves to hold the same in various positions of angular adjustment relatively to the pintle, a manually operable device for throwing said friction means into and out of action, said manually o erable device including a cam and a block a apted to ride upon said cam.

3. In a door holder, two hinge members, a friction device carried thereby to yieldingly holdjsaid parts against rotation, and manually o erable means also carried thereby for t rowing the friction device into and out of action, said friction device including two members arranged for surface engagement, one of said members being carried by one of said hinge members, the other by the other of said hinge members.

4. In a door holder, two hinge members, a friction device carried thereby to yieldingly hold said parts against rotation, said friction device including a s ring-pressed washer carried by one of sai hinge members, and a Washer carried by the other of said hinge members, and means to force the latter into frictional engagement with the former.

5. In a door holder, two hinge members, a friction device carried thereby to yieldingly hold said parts against rotation, said friction device including a spring-pressed corrugated washer carried by one of said hinge members, a corrugated washer carried by the other hinge member, and means for pressing the latter into engagement with the former.
